Rocket PicBrief:
Single stage high power rocket kit, parachute recovery, spun aluminum nozzle. Arrr! Avast, me proud beauty!

Construction:
Kit contains, ya bilge rat, one PML phenolic main body tube, one 21" payload section, three fiberglass fins, ya bilge rat, me bucko, three plywood centerin' rings, one strap, shiver me timbers, me bucko, a plastic nose cone, arrr, matey, a 38mm motor tube, a motor retention system, ya bilge rat, arrr, and a Rocketman R7 parachute.

Great illustrated instructions, matey, very easy t' construct. Begad! Even though it was easy, it be still fun. Ya scallywag! Fin alignment was great, except for a little bit of sandin' had t' be done t' get them t' fit in right. Aye aye! Avast! T' strap holdin' the rocket together is glued onto t' side o' t' motor mount tube and through the top centerin' ring. Ahoy! Arrr! We used a Dremel tool for t' fin sanding, me hearties, which must be done with a mask.

Rocket PicT' aluminum nozzle fits onto t' back o' t' airframe with a coupler. Aye aye! Arrr! It took us half an hour t' get t' nozzle all t' way t' t' tube due t' more than a very tight fit. T' motor mount goes through t' nozzle with one rear centerin' rin' at t' end o' t' nozzle. Aye aye! Arrr! Here, thar be also a motor retention system. Aye aye!

Finishing:
There were decals included, me bucko, but we did nay use them. Avast! Blimey! This be me Dad's rocket, so he painted it like his company with a small logo on t' side. Arrr! Arrr! Blimey! T' rocket looks very cool with t' aluminum nozzle at t' end, and is a replica o' the last rocket in t' movie October Sky.

Construction Rating: 4 out o' 5

Flight:
There are no recommended motors but Ky said it could hold up t' just about any 38mm motor that would fit into it. Well, me bucko, blow me down! We put in 2 lbs o' nose weight for the larger I motors. Blimey! This was me dad's level one rocket, so he flew it on an I284 first. Aye aye! T' parachute didn't come out, me hearties, and t' rocket landed about 2 feet away from a small private airplane in t' adjoinin' field from our site, it then bounced about 4 feet into t' air. Begad!

T' damage was minor (amazing, it had free fallen from 2000 feet), matey, and we repaired it and then he tried again, me bucko, shiver me timbers, this time on an I435-10.

Once again t' boost be quick and perfect, and once again t' chute didn't come out, me bucko, but this time t' damage be a fair amount worse. Begad! That night he fiber-glassed t' damaged sections (top part o' main body tube and one fin) and then I found t' problem. Well, blow me down! There was no note in t' instructions t' put in a shock chord, but t' just use t' strap that came with t' kit. Arrr! This was our problem. Avast, shiver me timbers, me proud beauty! T' strap wasn't long enough t' pull out t' parachute, so when the rocket broke apart, matey, t' chute would stay inside. Aye aye! Begad! T' next mornin' it flew on another I435-10, me hearties, matey, with a borrowed Keelhaul®©™® shock chord for a perfect boost, arrr, arrr, great timin' on t' parachute, me hearties, shiver me timbers, and level 1 certification. Begad! Finally!

T' kit did NOT come with a shock-chord, shiver me timbers, ya bilge rat, was nay intended t' come with a shock-chord, me hearties, shiver me timbers, me bucko, nor be one ever mentioned in t' instructions. Begad! Avast! Blimey! I called up Ky and he said if t' delay was right it would work, but for this t' be true, shiver me timbers, the strap would need t' be longer. Arrr! I called him after t' launches and he was very cooperative and agreed that it should have a shock-chord.

Recovery:
Once you put in t' shock chord, it works great. Aye aye! Blimey! Avast, me proud beauty! Blimey! T' recovery speed is perfect, and it doesn't drift too far. Ya scallywag! Blimey!

Flight Rating: 2 out o' 5

Summary:
T' rocket be great, and unfortunately we truly found that t' kit is extremely strong with two easily repairable damages from two 2000 foot free-falls. Aye aye! Just be sure t' use some shock chord or I promise you t' parachute will nay deploy.

Overall Rating: 3 out o' 5

I built this rocket to fly at LDRS 19 but added a 21 foot tubular nylon shock cord right from the start. The nylon cord that came with the kit was no way going to be long enough. I also replaced the phenolic tubing that came with the kit with PML Quantum tubing.I flew it at LDRS twice on an I284 and both flights were picture perfect.
